Agbada is one of the formation features that is characteristic of the Niger delta and JDZ.
From the JDA site:
"These are underlain by the Agbada Fm of paralic, brackish to marine, coastal and fluvio-marine deposits, organized into coarsening upwards ‘offlap’ cycles. The underlying Akata Fm, comprises up to 6500m of marine pro-delta clays. Shales of the Akata Fm are overpressured and have deformed in response to delta progradation. These shales facilitate regional decollement for updip extension and downdip compression. Shales of the Akata Fm constitute a world-class source rock."
